To be able to write in Photoshop/CorelDraw using Bangle, you need to install the required fonts. To do this, obtain the Bangla fonts and then go to Start > Run and type fonts. Drag and drop the TTF (fonts) into this folder and wait for installation to complete, then open Photoshop or CorelDraw and use the Text tool to insert text and select Bangla as font, then you can enter any word or Bangla character you want.
